modifications were relatively minor - mostly changes in function
names or arguments.

  (it grows anyway).
Fix state read logic to better handle error conditions.

Fix update node RPC to handle reason field change without state change.
  State was being handled as type int instead of uint16_t so NO_VAL check
  was not working properly.

"Scontrol abort" works. It was leaving a hung pthread due to a recent
   change.
Fix a couple of potential memory leaks
"switch_type" has been added to config data structure, un/pack, etc,
   but not yet reported to the user or documented yet.
The plugins now use function calls to get a their type and plugin directory
   from a common data structure rather than individually reading and
   parsing the configuration file.

 - move elanhosts.[ch] to common
 - initialize elanhost_config on demand in qsw.c
 - remove calls to elanhosts in slurmd/elan_interconnect.c
 - merge libhostlist into libcommon since elanhosts needs it.

wait for modifications to srun and its communications protocol.

sharing via node record of job count (0 | 1) and bitmap of nodes which
permit sharing. Previous logic could permit a job accepting shared nodes
to be scheduled on a node that already had a running job not accepting
shared nodes.

exit rather than log with error() and continue (which causes abnormal behavior).

 o more fixes for setenvpf() corner cases
 o move tmpdir logic up so it is not executed unecessarily for every task.
 o add getenvp() call to setenvpf.c
